Details

Successor to the APO MACRO 150mm F2.8 EX DG HSM, introduced to market in October 2004, this new OS design offers the latest optical technology. A floating focusing system moves two different lens groups in the optical path to different positions. This system compensates for astigmatic aberration and spherical aberration and provides extremely high optical performance from infinity to 1:1 Macro.

Features

F2.8 large aperture tele-macro lens

Life-size macro capability

Optical Stabiliser

SLD glass and Super Multi Layer Coating

Hyper Sonic Motor (HSM) with manual focus override

Floating Focusing System

SLD glass and Super Multi Layer Coating

Three SLD (Special Low Dispersion) glass elements provide excellent correction of all types of aberrations and the Super Multi-Layer Coating reduces flare and ghosting. This lens has superior peripheral brightness and provides sharp, high contrast images even at the maximum apertures.

Optical Stabiliser

Equipped with Sigma’s proprietary OS (Optical Stabiliser) function, this lens offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible.

F2.8 large aperture tele-macro lens

Tele macro lenses have a greater working distance. It is possible to enjoy Macro photography, even when you are far from subject. This enables you to capture the small animals and insects without disturbing them. Very narrow depth-of-field allows selective focusing and less distracting backgrounds. Large aperture of F2.8 is ideal for sports, action and indoor photography.

Hyper Sonic Motor (HSM) with full time manual focus override

The HSM (Hyper Sonic Motor) ensures quiet and high speed autofocus as well as full-time manual focus capability.

Floating Focusing System produces excellent optical performance

A floating focusing system moves two different lens groups in the optical system to different positions. This system compensates for astigmatic aberration and spherical aberration. Since focusing does not change its overall length, this lens is easy to hold and use.

Rounded 9 blade aperture ring

This lens has a rounded 9 blade diaphragm creating a smooth blur to the out of focus areas of the image. It is also possible to use this lens with Sigma’s optional APO Tele Converters.
